What makes a moguls run a DNF?

I · Intermediate · Moguls and aerials · 3 of 6

Checked 14 October 2026

A moguls course has two jumps, and a skier must do two different jumps to earn full air marks. Missing a control gate, losing a ski or stopping for 10 seconds ends the run as a DNF. A skier who has a DNF must leave the course; going back in to finish the run brings a disqualification.

How it works

Two jumps: each must be different to earn full marks.
Different: different category, direction, rotation by 360 degrees or number of moves.
Grabs: a grab can make a same-category jump different, but both take the lower DD.
Only one jump: at most half the air score.
Gate: both ski tips and both feet must cross the gate line between the inside poles.
Gate fault: a DNF; climbing back is not allowed.
Lost ski or 10-second stop: a DNF; a lost pole is not.
Re-entering after a DNF: a DSQ and possibly a fine.

The glossary has the different jumps, the control gates, the degree of difficulty, the twisting double, the moguls and the air bumps.

Tricky cases

A skier does three jumps. Which count?

The two highest scoring; the lowest is disregarded.

A skier drops a pole. Is that a DNF?

No. Losing a pole does not cause a DNF if they finish.

Can two back flips both count?

Only if one adds rotation, such as a full twist, or they start in different directions.

A skier misses a gate and climbs back. Is that allowed?

No. They must leave the course and ski down outside it.

Why the rule exists

Requiring different jumps rewards range, as in other freestyle events. Gates keep skiers on the bumps, so no one gains by skiing the smoother side.
